1999 Powered Mirror Wiring Diagram

One of my kids recently hit a construction barrel and knocked off the right side powered, heated mirror. Also missing is the connector from the car's wiring harness. What I see are three wires....however the new mirror has five wires going into the connector. Since I cannot buy the car side connector, I thought of just direct wiring to the mirror. So my question is does anyone know what three wires connects to the mirror's wire...or does anyone have a wiring diagram for this? Thanks...Bruce
